How do I know if I need the 2026 or 2025 version?

Check the serial number on your bidet seat. The first four digits are a date code in MMYY format. If it reads 0825 or higher, you need the 2026 version. Codes before 0825 require the 2025 version.

Can I use this lid on an elongated toilet bowl?

No, this lid is sized and shaped for round bowls only. Elongated bowls require a different lid profile with longer dimensions.

Will this fit other bidet seat brands?

No, it is designed exclusively for TUSHY Wave and Oasis models and uses a proprietary sliding lock attachment system.

Do I need tools to install this lid?

No, installation uses a sliding lock mechanism that engages by hand. You unlock the slider, align the lid, and lock it back into place.

Round Soft-Close Lid for Wave/Oasis (2026 Version)

Most bidet seat lids can't be replaced separately; you either live with a cracked hinge or buy the whole assembly again. This component swaps independently because the mounting uses a slider instead of permanent fasteners, which means a dropped weight or accidental knee doesn't sentence the entire seat to a landfill.

That modularity also lets you correct a bowl-shape mismatch without discarding working parts. If you ordered an elongated seat for a round bowl, you can buy the matching round lid and seat together, then keep the leftover elongated pair for a future bathroom. The lock mechanism is the same across shapes, so swapping takes the same few minutes either way.

The details

This replacement lid fits round-bowl configurations of the Wave and Oasis bidet seats manufactured from August 2025 forward. The soft-close mechanism prevents slamming, and the component detaches using a sliding lock mechanism that lets you swap parts without removing the entire seat assembly.

Compatibility depends on a four-digit date code in your bidet seat's serial number. Units with codes 0825 or later require this 2026-version lid; earlier codes need a different part. The serial number is stamped on the bidet seat itself, and the first four digits indicate month and year in MMYY format.

The lid measures 18.5 inches long by 14.7 inches wide, matching the round-bowl footprint. Installation reverses the removal process: unlock the slider, align the lid with its mounting points, and lock it back into place. The soft-close hinge provides gradual, controlled lowering from any release angle.

This is the same component that ships standard with new units. It works only with Wave and Oasis models, not with other bidet seat brands or standalone classic bidet attachments. Bowl shape matters—elongated bowls require a different lid profile even within the same model line.
